Description

The present invention relates to a kana-kanji conversion method and apparatus for converting an input kana character string into a kanji-kana mixed sentence.

(B) Conventional technology Conventionally, in a document processing apparatus having a kana-kanji conversion function of this type, a dictionary for kana-kanji conversion is provided.

The words registered in this dictionary are usually general words, and a specialized dictionary is provided with a user dictionary so that a user can newly register words.
Since the words registered in the user dictionary are words used by the user, they usually have a higher output priority than the words registered in the general dictionary.

(C) Problems to be Solved by the Invention However, there are words that the user wants a word but does not necessarily want to appear first. In addition, since words have been registered in the user dictionary, a character string that has been output correctly up to now may not be output. , Process, affirmation, emperor, school revision, high and low "are registered, and if" revision "is newly registered here," revision "will be output more strongly than the other words" kouta ".

In the latter case, by registering "Ujiko = Ujiko" in the user dictionary, if the character string of "Kuko Ujiko" was converted to "Aircraft accident" until now, "Ujiko" Is strong, there is a possibility that the output will be "School District Fellow".

The present invention has been made in consideration of such circumstances, and when registering a word in a user dictionary,
At the time other than single-segment conversion, that is, at the time of multiple-segment conversion or multiple-segment conversion at the same time, by adding a recognition flag indicating that conversion is not to be performed, adverse effects during conversion were prevented, and conversion efficiency was improved. A kana-kanji conversion method and apparatus are provided.

(D) Means for Solving the Problems The present invention relates to a general dictionary that stores a large number of words together with their reading information, and a user dictionary that registers a word specified by a user in association with reading information and identification information. Is used to convert the input Kana character string to Kana-Kanji conversion, input the Kana character string, store the input Kana character string, divide the stored Kana character string into phrase units, The conversion candidate is searched from the general dictionary and the user dictionary in units of, and it is determined whether the searched conversion candidate includes the user dictionary conversion candidate with identification information, and the division result is a plurality of phrases. At this time, there is provided a kana-kanji conversion method characterized by outputting only conversion candidates other than the user dictionary conversion candidates with identification information.

In addition, as shown in FIG. 1, the present invention provides a general dictionary 101 that stores a large number of words together with their reading information, and a user dictionary that registers a word specified by a user in association with reading information and identification information. 102, an input means 103 for inputting a kana character string, a storage means 104 for storing the input kana character string, a dividing means 105 for dividing the stored kana character string in units of phrases, Search means 106 for searching for conversion candidates from the general dictionary 101 and the user dictionary 102 in units, and judging means 107 for judging whether the searched conversion candidates include a user dictionary conversion candidate with identification information. And a kana-kanji conversion device characterized by comprising output means 108 for outputting only conversion candidates other than the user dictionary conversion candidates with identification information when the division result is a plurality of phrases. General dictionary section 101 and user dictionary section 1 in Ming
02 may be anything that can store a large number of reading information, notation, semantic classification and examples of words including kanji for each word,
It is composed of a large-capacity ROM, a magnetic storage medium such as a floppy disk or a hard disk, and a drive unit for the medium.

As the input unit 103, the storage unit 104, and the output unit 108, those known in the art can be used. For example, the input means 103 may be any device capable of inputting a kana character string.
A display device such as a CRT and an LCD is used as the AM and the output means 108, respectively.

It is convenient to use a microcomputer having a CPU, a ROM, a RAM, an I / O port, and the like as the dividing unit 105, the searching unit 106, and the service determining unit 107.

(E) Function According to the present invention, when the input kana character string is a plurality of phrases, only conversion candidates other than the user dictionary conversion candidate with identification information are output, thereby providing kana-kanji conversion. The conversion efficiency of kana-kanji conversion can be improved by preventing the adverse effects.

(F) Embodiment Hereinafter, the present invention will be described in detail based on an embodiment shown in the drawings. Note that the present invention is not limited to this.

FIG. 2 is a block diagram showing a configuration of an embodiment in which the present invention is applied to a Japanese word processor.

In FIG. 1, reference numeral 1 denotes a keyboard provided with kana keys, function keys, and the like, and inputs a kana character string to the control unit 2.

The control unit 2 is composed of a microcomputer and has a RO
Various data processing is performed according to the control program written in the program memory 3 composed of M.

Reference numeral 4 denotes a kana-kanji conversion dictionary comprising a floppy disk device for converting a kana character string input from the keyboard 1 into a kanji-kana mixed sentence. Kana-Kanji conversion dictionary 4
Is composed of a general dictionary unit 5 that stores a large number of words together with their reading information, and a user dictionary unit 6 that registers a word specified by the user in association with the reading information.

 Reference numeral 7 denotes a display device including a CRT display device.

Reference numeral 8 denotes a sentence memory composed of a RAM for storing document data converted into kana-kanji characters.

FIG. 3 is an explanatory diagram showing an example of a registration screen in the case of registering a word in the user dictionary unit 6. As shown in FIG. 3, when a word is registered in the user dictionary unit 6, for example, "Ujiko" If you register the word, headline → “Ujiko” Registered word → “Ujiko” Part of speech → “Noun” Register and convert multiple phrases at once (multi-phrase conversion, continuous phrase conversion, etc.) For example, if the user does not want to use the target character, a "x" mark is input after the "part of speech". Thereby, a recognition flag as an identification code is added to a word registered in the user dictionary unit 6.

FIG. 4 is an explanatory diagram showing an example of registration in the user dictionary unit 6. As shown in FIG. 4, in the user dictionary unit 6, the recognition flag “1” is assigned to a word to be subjected to batch conversion, and Words that do not have a recognition flag “0” are added to each word.

For example, a case will be described in which a kana character string such as “Kokuujiji” as shown in FIG. 5 is input and Kana-Kanji conversion is performed on this character string.

When a kana character string of “Koji Ujiko” is input, the control unit 2 extracts a preceding phrase and a following phrase, and selects a plurality of candidates. In the normal processing, since the connection between two kanji characters is strong, if "Ushiko" is not registered in the user dictionary unit 6, it is squeezed as a candidate for "aviation, high sky + accident, self" and frequency information is considered. "Aircraft + accident"
Are output in association with each other.

However, if "Fuji" is registered in the user dictionary unit 6, a candidate for "School zone, construction zone + Fiji" is also selected. In this case, if the character example "Koku Ujiko" is input, if there is a promise (composite example) to output "Airline + Accident", there is no problem even if "Mr. Ushiko" is registered. If there is no promise, the words registered in the user dictionary unit 6 are output more strongly, so that there is a high possibility that the words are converted to “school zone + shiko” in order to output “shiko”.

For this reason, if it is known that “Mr.” has an adverse effect, or at the time when it is known, the recognition flag of the user dictionary unit 6 is set to OFF (0). In that case, "Ushiko" will not be the symmetry of multiple phrase batch conversion, so "Airline + accident"
Can be output.

Next, the contents of the processing operation of the control unit 2 are described in the sixth.
The description will be made according to the flowchart shown in FIG.

For the kana-kanji conversion character, first, an input kana character string is taken in (step 201), a preceding phrase is extracted (step 202), a subsequent phrase is extracted (step 203), and the general dictionary unit 5 and the user dictionary are extracted. Then, a two-segment process is performed with reference to step 6 (step 204). This is repeated until the end of the sentence (step 206), and the same phoneme is selected (step 207). When the sentence ends (step 208), the kana-kanji conversion is completed. By attaching a recognition flag to the words registered in 6 that the multiple-phrase batch conversion characters are not subject to conversion, it is possible to prevent a reduction in conversion efficiency of kana-kanji conversion characters caused by registering words in the user dictionary unit 6. can do.

(G) Effects of the Invention According to the present invention, when an input kana character string is a plurality of phrases, only conversion candidates other than the user dictionary conversion candidates to which identification information is added are output. The conversion efficiency of kana-kanji conversion can be improved by preventing adverse effects of time.
